Has to be Legend of Kyrandia I. Old, weird game. It was strangely appealing to me at that time. I developed cravings for berries while playing that game.

If you feed the main character a fireberry, it burns his mouth. If you feed him a blueberry, you hear a gulp sound, and he says 'crunchy'. There are also gems and other fruits lying around or on trees in the forest. If he gets lost in the cave maze when his fireberry burns out, he gets eaten by monsters or something. So he has to get to other fireberry locations in the cavern before his fireberries burn out.

That's gotta be it, Becky. The irritating thing about that game was that even though you had plenty of clues about what was really going on - you had no meaningful alternatives :/

The drama in that game was incredible, as I remember. Some decent acting & set designs in that one. The music section was quite amusing and was worked in well. Offered some nice relief from the general tension. Remember how freaky it was when the ghost would suddenly try to warn you - with her violin playing and all that? Very well done!
